WINDOW CURTAIN CORNICE.

SPECIFICATION forming part of Letters Patent No. 279,232, dated June 12, 1883. Application filed December 27, 1885.. (No model.)

T0 all whom t may con/cern:

Be it known that I, CvnUs EBERLY, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in lVindow Curtain Cornices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to the class of window curtain cornices composed of a stationary center piece and sliding sides or wings moving in grooves or ways of said center piece, and operated by an endless cord secured to the inner ends of the side pieces and passing around pulleys at the ends ot' the center piece. y

The object of the invention is to dispense with the pulleys heretofore employed for the guidance of the endless cord, thereby making a cornice of the class above mentioned more simple in construction and less expensive than heretofore.

The invention consists in the provision of bridge piecesor plates, made of metal, wood, glass, or other suitable material, which are secured to the back side of the stationary center piece, and have formed therein or Athereon fixed curved guide grooves or ways for thereception and guidance of the endless cord connected with the adjustable wings. These bridge-plates are located at the ends of the center piece and extend across the groove or way in which the adjustable wings slide, and serve to hold the latter in place.

In the drawings, Figure l is a rear view of an extensible cornice, showing metallic bridgeplates provided with cordways or grooves, which are formed by turning-up a series of prongs on the side of each bridge-piece. Fig.V 2 is a perspective view of one of said metallic bridge-plates. Fig. 3 is a rear view of a cornice having wooden bridge-pieces with curved or semicircul ar cord-grooves cut-in their faces.

The letter A designates a stationary center piece, which has a groove or way onits rear i'ace for the reception and retention of the ex` tensible side pieces, B. Theseside pieces are connected together by the endless cord C, so as to allow them to be extended evenly and sinniltaneously and cause the center piece to always remain exactly in the middle of the window or other casing to which the cornice is applied. The endless cord is secured to the extensible arms at their inner or meeting ends, as is shown at a, and itpassesaround curved or semicircular guide grooves or ways D, formed on or in bridge-plates E, which are secured to the center piece, A.

As shown in Figs. l and 2, the guideway for the endless cord is formed on a sheet-metal plate by cutting out a series of prongs or spurs, F,iat the vedge of said plate, and asthese prongs are cut on a semicircular or curved line, they will, when turned up or bent over,

form a groove or way in which the cord is re-.

tained and can freely move. The bridgeplates E are located at the ends of the center piece, and, in additionto being provided with the cord-grooves, as stated, they hol d the sliding sections or arms in place. l

In the construction shown in Figsx to 5, inclusive, the bridge-plate is made with a curved or semieircular groove, G, which is sunk Vinto the face of the plate, and has the edges or-walls thereof cut obliquely, or on a bevel, as is clearly shown in Fig. 4. In other words, the groove is undercut, or is of a dovetail shape, so that the cord will remain secu rely seated therein.

The bridge-plateshown in Figs. 3, 4, and 5 is generally made of wood; but it may be of metal, glass, or any other suitable material.

Vhat I claim as my invention, and desire to secure by Letters Patent, is l. In an extensible window curtain or other cornice, the combination of bridge or back plates, having fixed or stationary semicircular or curved grooves or ways formed therein or thereon, with the stationary center piece, extensible side arms, and endless operating-cord secured to sind Side arms und moving in the In testimony whereof I afflx my sgnanre in ways or grooves of the bridge-plates, Substanpresence of two Witnesses. tially as herein set forth.
